When they brought it to light, archaeologists called it "the little Petra of Populonia". It is actually an ancient rocky necropolis, which the Etruscans of the only city founded by the sea built between the fourth and third centuries BC, reusing a front of a sandstone quarry. You will find it inside the Archaeological Park, facing the splendid Gulf of Baratti, after about half an hour’s walk through the typical Mediterranean "macchia". Among holm oaks and cork oaks, among tombs and quarry blocks, climbing slowly you will reach the Belvedere, a panoramic point of extraordinary suggestion: from up there the view is lost between the sea and gentle hills, up to the hills of Campiglia from where the Etruscans extracted copper and tin.
